Stack tree
 | This article may be confusing or unclear to readers. (December 2006) |
A stack tree is a binary tree where no node besides the root has more than one non-leaf child. As the elements of a binary tree have 2 children, this means that one points to the next node (and hence is a non-leaf child) and one points to a data element, or NULL. Hence the tree is essentially a singly linked linked list, with data items hanging off each node.
